SGRAPER FOR GOLTERS.

Specification of Letters Patent.

Application filed December 23, 1914. Serial No. 878,788.

To all whom it may concern Be it known that T, VVALDO J. LEE, a subjectof the King of Great Britain, residing at Munson, in the Province ofAlberta, and the Dominion of Canada, have invented a new and usefulImprovement in Scrapers for Colters, of which the following is aspecification.

This invention relates to an adjustable scraper for rolling colters.These colters traveling through sod or previously cropped lands collectnot only damp earth, but more or less remains of vegetation, such as sodroots, straw, or fibers of plants such as flax, and such accumulationinterferes with the clean cutting operation of the disk.

The object of this invention is a scraper adapted to be quickly appliedto colters of various sizes and types of frame, and which may beadjusted to suit such varying sizes and types, and. which willautomatically keep the cutting edges of the colter clean.

The invention consists of the novel features of construction hereinafterpointed out, set forth in the claims and shown in the accompanyingdrawings in which:-

Figure 1 is a side elevation. Fig. 2 isia plan view. Fig. 3 is a frontsectional view. Fig. 4 is an inverted plan view of a clamping plate.Fig. 5 is a section on the line 55 of Fig. 4. Fig. 6 is a perspectiveview of a slotted wedge.

In these drawings-1 represents a rolling colter journaled between theforks of a bifurcated frame 2, in the usual manner.

Extending transversely across this frame" are upper and lower bars 3,bolted together and suitably slotted to allow for varying widths offorks. 1

To enable these bars to rest firmly upon forks which may be more or lessirregular in surface, or rounded I employ, where necessary slottedwedges 4 which are placed between the bars and the fork, and throughwhich the securing bolts 3 pass. Clamped on the top of the fork andunder the upper bar 3 is a plate '5 the forward portion of which is cutout midway its ends as shown at 6 to receive the colter, and upon eitherside of this cut out portion the late is transversely slotted as shownat The body of the plate is'flanged or vrecessed out Patented July 2?,T915.

on its under face as shown in Figs. 4:. and 5,

versely on the plate 5, and on opposite sides of and in engagement withthe colter. These plates are slotted as shown at 9 and bolts 10 workingthrough the slots 7 and 9 hold the plates 5 and 8 together. As the slots7 and 9 are at right angles to each other, adjustment of the scrapers intwo directions, 1on gitudinally and transversely, is provided.

The uses and advantages of a device of this kind will be obvious:

To prevent loss of the wedges chains 4 may be connected to them asshown-in Fig. (3, and the chains carry rings 4" through which the bolts3 are adapted to pass.

What I claim is:-

1. The combination with afork and a colter journaled therein, of acentrally cut out and transversely slotted plate held on said fork, andtransversely slotted scraper plates adjustably mounted on the firstmentioned plate and overlapping the cut out portion, the scraper platesbeing adapted to "engage the sides of the colter.

2. The combination with-a rolling colter and its forked frame, of barsarranged transversely on the frame and longitudinally slotted, boltsconnecting said bars, a longitudinally slotted and centrally cut outplate held between one of said bars and the frame, scraper platesarranged on and at and scrapers carried by said plate.
